Glad Valley anchors the southeastern portion of this landscape, situated near the boundary between Ziebach and Corson counties. The terrain is characterized by the intricate drainage systems of Twin Butte Cr and its tributaries, including E Fork E Twin Butte Cr and W Fork E Twin Butte Cr, which carve through the plains. In the northern reaches, the Grand River National Grassland encompasses a significant portion of the territory, reflecting the federal management of these public lands. Rural infrastructure is sparse, defined primarily by a grid of section lines and thoroughfares like 215th Ave, which facilitate movement through this remote ranching and grazing country.
